While apostolic succession looks like nice concept on paper, it's something impossible to verify for a single Christian human. I have no way to tell, if the Great Schism even happened how it's reported (like on Wikipedia) and if the Pope of current era RCC is even the real Pope or just a deception of an imposter. So all I can depend on is on our Lord Jesus Christ Himself.
Pure gnosticism. There's little difference from the atheist skeptic says "while the resurrection of Jesus looks like a nice concept on paper, it's something impossible to verify for a single human." The difference is only a matter of degree. The natural next step is to ask, why can we even trust the Bible? At least the Enlightenment Humanists and their fedora-doffing descendants were intellectually consistent: they rejected the Church that compiled and canonized the Scriptures, so rejecting the authority of Scripture naturally follows from that.
If you believe Jesus meant it when he said that He would establish His Church and the gates of hell would not prevail against it (Matthew 16.18), it matters a lot because managing to maintain your faith and practices for well over a millennium lends some credence to the idea that this is the Church Jesus was describing, and Independent Fundamentalist Pastor Billy Bob's church that collapses after the ambitious music minister drives him away in a hostile takeover is not. Besides that, Scripture itself tells us that we can rely on the Church, which St. Paul calls the "pillar and ground of truth" (2 Thess. 2.15).
And don't bother giving me the line about the "invisible church,"
it's already been thoroughly dismantled.
Matthew 7:15 - You will know them by their fruits: How do they conduct their lives? Are they living in perpetual sin? Do they show the fruits of Spirit (Galatians 5:22) or are they SJW-type shrieks?
Mormons always seem incredibly nice and seem to show spiritual fruit, especially compared to the IFB crowd. Perhaps I should join their church.
Lots of nice, sincere people believe things that aren't true. Just because Barbara the Calvinist lady brings me nice cookies every once in a while, that doesn't make Calvinism correct, especially when Josh The TULIP Cultivator counteracts her as he shrieks at me about this thing or that from Calvin's Institutes. And none of the protestant churches I attended produced anything like Orthodox Saints, whose lives are inspiring and encouraging.
As the goal is saving souls, boasting of being around for so-and-so-thousand years is not really required.
And a Mormon or Jehovah's Witness would say the exact same thing to justify their theological novelties and disconnect from historical Christian belief and practice.
If the Church is meant to play a role in salvation as most Christians believed for the past two thousand years than it actually matters a lot. IFB types think that the most important thing is going door-to-door, salesman-style, "preaching the Gospel" at people, but in all my years as a Christian I have yet to meet a single person who actually became a Christian this way. This hyper-individualist model of Christianity is a historical novelty with no basis in the Patristic writings or pre-Schism Church.
Worrying about "investments" in life is very human thing. Who wants to go to college and then realize, that it was all in vain? However as Christians we store up treasures in heaven, not on earth (Matthew 6:19-21), and nothing you do for the Lord is in vain. Even if a church blooming with life closes and disappears over night, some people still got saved.
What a bleak perspective. You're conflating earthly investments with spiritual investments, and investing in your church
IS storing up treasures in heaven. You just made the exact opposite point of what you wanted. This is just individualist pseudo-gnosticism, where no element of the Christian faith outside of the individual's rationalistic assent is real. Christianity and the Church is reduced from a real, tactile thing reflective of a God who became a real, actual man, into a theoretical philosophy and set of mental propositions with little connection to the real world.
This ends-justifies-the-means way of thinking about the Christian faith is a complete disaster,
and is the direct origin of the theological compromise, marxism, and relativism running rampant in protestant churches today. If anything goes as long as "some people still got saved," then terrible power ballad worship songs
and endless marketing gimmicks are the inevitable result; and at worst, you get female pastors, BLM parroting, and homosexual acceptance since the last thing you'd want to do is "push people away." And from an Orthodox perspective - the one held by posters of this sub-forum - you most definitely
don't know that those "people still got saved," and the plight of their church might have an adverse impact on the odds of that.
